The Honeywell VRN2DQSXC000 is a pressure independent control valve assembly that effectively manages flow in hydronic systems. This assembly integrates both flow and temperature control, adjusting automatically to maintain the desired temperature under varying pressure conditions. It is equipped with an integrated pressure control cartridge that enhances flow balancing and ensures optimal performance.
Features a 2-way valve with stainless steel trim and NPT connection.
Designed for floating on/off control with fail-in-place functionality.
Compatible with Honeywell N05/S05-series direct coupled actuators.
Product Highlights
This assembly is suitable for use with water or glycol solutions up to fifty percent concentration. Its robust design makes it ideal for a variety of applications, including hydraulics and pneumatics. The electric actuator and two auxiliary switches allow for efficient operation and monitoring.
